2. Locate the vehicle’s A/C low-pressure service port and remove and save the protective cap. The low-pressure service port is located on the large diameter metal tubing that runs from the evaporator (inside the dashboard) to the A/C compressor. Visit our port locator at www.acprocold.com for additional help locating your low pressure service port.3. With A/C on determine if compressor clutch is engaged (cycled on). TIP: If the compressor is not cycling on, add ½ can of refrigerant using instruction below. If the compressor still does not engage repairs may be necessary.
If the pressure is below the range outlined by the “V”, continue per below charging instructions. If the compressor is cycled on and the pressure is in the red do not attempt to recharge, seek professional service. Detach quick-connect fitting from low-pressure service port.TIP: YOU CAN ALSO REFER TO AMBIENT TEMPERATURE CHART FOR CORRECT TEMPERATURE/PRESSURE READING.
1. Shake can well.
2. Screw can into hose assembly and reconnect quick-connect to low pressure port.
3. Squeeze the trigger of the charging device to begin charging. Notice the gauge needle goes to zero to indicate no pressure reading is being taken during charging.
4. While charging, rotate the can between 12 o’clock and 3 o’clock every 2 to 3 seconds while continually shaking the can back and forth.
5. Every 10-15 seconds, release the trigger to check the pressure reading. Notice the gauge needle shows the A/C system pressure. System is charged when the gauge needle reaches inside the red “V” area marked on the lens. Frequently check the air blowing out of the dashboard vent.
6. Continue this process until the system is fully charged (PSI in GREEN zone) or can is empty. If can is empty, turn upside down for 1 minute to dispense any remaining contents before removing from port. DO NOT OVERCHARGE THE SYSTEM!
7. When finished, remove the quick connect fitting from the low-pressure service port. You may either keep the hose and can assembled tightly on can or if empty, unscrew the hose assembly from the can and discard. Replace the protective service port cap removed during step #2.
STORE OR RECYCLE REMAINING CONTENTS
Do Not Discard Remaining Contents!
Store it in a cool dry place for future use.
AMBIENT TEMPERATURE PRESSURE GAUGE CHART
Ambient temperature refers to the outside air temperature surrounding the vehicle. The chart shows the desired range for the low-pressure side of the A/C system at each 5º increment. If the pressure is outside of the range (over or under), service may be required.
NOTE: Pressure reading can only be taken when the compressor is cycled on. To determine this, look at center of the compressor’s pulley, If rotating, it’s on. If it won’t engage, add a can of R-134a. If compressor still won’t cycle on, seek professional service.
• Keep out of reach of children!
• Do not run vehicle in a closed garage!
• Wear protective gloves and safety goggles!
• It is illegal to vent refrigerant into the atmosphere!
• Before using these products, check all warnings and consult the
owner’s vehicle service manual!
• Our couplings are designed to exclusively mate with an automobile’s R-134a A/C system low-pressure port only. Do not attempt to modify this product in order to connect with any other A/C port as this may cause refrigerant cans to explode.
• Do not store cans in vehicle or expose to temperatures above 120° F!
Can will burst above 120° F!
• Do not puncture or incinerate a can.
• If sprayed into eyes or skin, flush with plenty of warm water. Get medical
attention immediately. Product can cause frostbite.
• If swallowed or inhaled see a physician immediately. Inhalation can cause
death without warning.
